my parents came from the philippines, immigrated here for better opportunity. in general, i am glad to see people, regardless of their race or creed or whatever, getting more involved in politics and just this debate. any differences i have with president obama and the administration has nothing to do with race or who he is or his personality. personal things. they have to do with issues of substance. substantive difference is a matter of policy. that is what a debate needs to be. i'm happy to engage with folks on issues of substance, but you know, certainly -- of course there will be people out there, i am not one of them, who do not like obama for really personal and probably wrongheaded reasons, but i try to be a constructive critic. i think the president has done some good things and he has done things that could have been done better, but that is the case with any president. host: what about mr. rouhani -- hassan rouhani? how is he different than the previous president? does that change negotiations with iran, and should we change that tack because of him?
